Abstract

A level shifter includes an input circuit having first and second input terminals configured to receive complementary input signals at a first voltage level and a second voltage level. A cross-latch circuit is coupled to the input circuit, and has first and second output terminals configured to provide complementary output signals at a third voltage level and a fourth voltage level. The input circuit includes first and second control nodes configured to output first and second control signals at the first voltage level and the fourth voltage level based on the input signals. A tracking circuit is coupled to the input circuit and the cross-latch circuit, and is configured to input first and second tracking signals to the cross-latch circuit based on the first and second control signals, wherein the first tracking signal is the greater of the first control signal and the third voltage level, and the second tracking signal is the greater of the second control signal and the third voltage level.
